  2. 1. Fungal taxonomy and systematics in the digital era, with an outlook on the cantharelloid clade (Basidiomycota)

    Author : R. Henrik Nilsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cantharelloid clade; ectomycorrhiza; Agaricomycetes; phyloinformatics; barcoding;

    Abstract : Fungi form a large and ubiquitous group of organisms where species identification and delimitation on morphological grounds often fall short. DNA sequences have proved an invaluable information source for these pursuits and are now routinely used in most mycological laboratories. READ MORE

  4. 2. Phylogenetics and taxonomy of the Gorteria clade (Asteraceae-Arctotideae)

    Author : Frida Stångberg; Arne Anderberg; Christoph Oberprieler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; växtsystematik; Plant Systematics;

    Abstract : This thesis deals with the systematics of the Gorteria-Gazania-Hirpicium-clade within the tribe Arctotideae-Gorteriinae in the angiosperm family Asteraceae. The group is found in southern Africa, with many representatives in the Greater Cape Floristic Region in South Africa, an area known for its high species richness and endemism. READ MORE

  5. 3. Characterization of Campylobacter jejuni and Campylobacter coli water isolates

    Author : Anna Nilsson; Hilpi Rautelin; Astrid Skarp; Cecilia Johansson; Mikael Skurnik; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; C. jejuni; C. coli; C.coli clade 2; C. coli clade 3; waterborne pathogens; whole genome sequencing; water survival; pathogenic potential; phenotypical identification; Klinisk bakteriologi; Clinical Bacteriology; Medicinsk vetenskap; Medical Science;

    Abstract : Campylobacter jejuni and C. coli are together the most common cause of bacterial gastroenteritis in the European Union. Campylobacter can be transmitted to humans via contaminated water, but it is largely unknown how these bacteria survive in water. READ MORE

  6. 4. Systematics and biogeography of the South African Metalasia clade (Asteraceae-Gnaphalieae)

    Author : Annika Bengtson; Per Ola Karis; Anthony Verboom; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; växtsystematik; Plant Systematics;

    Abstract : The Metalasia clade (Asteraceae–Gnaphalieae) consisting of the genera Metalasia, Atrichantha, Calotesta, Dolichothrix, Hydroidea, Lachnospermum, Phaenocoma, and Planea is endemic to South Africa with a main distribution within the Cape Floristic Region (CFR), a region known for its remarkable botanical diversity.The monophyly of the Metalasia clade, the relationships of its genera, and the circumscription of these as well as their position within the tribe Gnaphalieae is investigated using molecular data.

  7. 5. HIV-1 phenotype and genetic variation in vertical transmission

    Author : Peter Clevestig; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV; co-receptor use; diversity; clade; sequon.;

    Abstract : HIV-1 vertical transmission is increasing worldwide despite that successful strategies are available. Reduction of vertical transmission has been established by antiretroviral prophylaxis and elective Caesarian section, but this has been limited to the developed countries. READ MORE
